# Attribution Windows: Default Click Lookback Windows

> The default click-to-install lookback windows Linkrunner uses per ad network, why Google and Meta are 30 days, and how to change them per project.

**A click window is how far back Linkrunner looks for a click when crediting a new install.** If the matching click is older than the window, it is not used, and the install is recorded as organic instead.

This is applied per ad network, so a click from Google Ads and a click from an affiliate can be judged against different windows.

## Default windows

| Ad network          | Default click window |
| :------------------ | :------------------- |
| Google Ads          | 30 days              |
| Meta                | 30 days              |
| Every other network | 7 days               |

Google and Meta default to 30 days because installs on those networks often report well after the click. Everything else defaults to 7 days.

These defaults apply automatically. You do not need to set anything to get them.

## Change a window

Go to **Settings → Attribution Windows** in the [dashboard](https://dashboard.linkrunner.io/dashboard/settings/attribution-windows).

The table starts empty and lists only the ad networks you have overridden. Everything not listed is running on the default from the table above.

Click **Add**, pick an ad network, enter a number of days, and save. The change applies to that ad network on this project only.

Use the edit icon on a row to change its number, and the delete icon to remove the override — that network goes back to its default.

Changes take effect within about five minutes.

## Limits

Windows can be set from **1 to 30 days**.

The 30 day ceiling is not arbitrary. Linkrunner retains clicks for 30 days, so a click older than that cannot be matched to an install at all, and a longer window would have no effect.

## What this does not cover

This setting governs **click matching only**. View-through and probabilistic attribution are not affected.

It is also separate from the **Lookback Window** on the Remarketing page. That one controls the reattribution window for users who already have your app. This one controls how a brand new install gets credited.
